Abstract
A power equipment protection system includes a plurality of trip units including at least a first trip unit and a second trip unit, wherein each of the plurality of trip units is configured to monitor operation data. The system also includes a shared memory device coupled to the plurality of trip units via a network, wherein the shared memory device is configured to transmit a synchronization request to at least the second trip unit, receive a response from the second trip unit, including operation data associated with the second trip unit, receive a data request from the first trip unit, and transmit the operation data associated with the second trip unit to the first trip unit via the network.
Claims20
A method comprising:
- receiving, by a shared memory device communicatively coupled to a first trip unit and a second trip unit of a plurality of trip units, a data request from the first trip unit for operation data associated with the second trip unit, each trip unit configured to collect operation data relating to a respective circuit breaker, wherein the shared memory device includes a memory area;
- locating the operation data associated with the second trip unit of the plurality of trip units in the memory area;
- and
- transmitting, from the memory area of the shared memory device, the operation data associated with the second trip unit to the first trip unit for use in a multi-point function performed by the first trip unit based on operation data relating to a plurality of circuit breakers.
A power equipment protection system comprising:
- a plurality of trip units comprising at least a first trip unit and a second trip unit, each of said plurality of trip units configured to monitor operation data relating to a respective circuit breaker;
- and
- a shared memory device communicatively coupled to said plurality of trip units via a network, said shared memory device configured to:
- transmit a synchronization request to at least said second trip unit;
- receive a response from said second trip unit, the response including operation data associated with a circuit breaker that is communicatively coupled to said second trip unit;
- receive a data request from said first trip unit for operation data associated with said second trip unit;
- and
- transmit the operation data associated with said second trip unit from said shared memory device to said first trip unit via said network.
A shared memory device for use with a power equipment protection system, said shared memory device coupled to at least a first trip unit and a second trip unit of a plurality of trip units, said shared memory device comprising:
- a memory area configured to store operation data associated with at least the first trip unit;
- and
- a processor coupled to said memory area and configured to:
- receive operation data from the first trip unit via a network;
- store the operation data in said memory area;
- and
- transmit the operation data from said memory area of said shared memory device via the network to the second trip unit.
